Toronto police say a 13-year-old girl was forced into prostitution after being lured on Facebook by a 17-year-old girl.

Three people have been charged with human trafficking offences, including the 17-year-old suspect. The victim was held captive for a month, Insp. Joanna Beaven-Desjardins told reporters on Friday. During that time, the people accused in the case forced the victim to have sex with clients in Niagara Falls, Toronto and Brampton. Beaven-Desjardins said the victim and the teenage suspect had mutual Facebook friends. After talking to each other on social media, police allege that the 17-year-old lured the victim to a meet-up with another one of the accused, 22-year-old Kahmal Howard Paris.

Police said it was during that meeting at Paris's Toronto home that the victim was told she would be taken to Niagara Falls to perform sexual services for clients.

US prosecutors say they plan to try a police officer for a third time for allegedly using excessive force against an Indian grandfather who was pushed to the ground while he went for a morning walk. Eric Parker has been tried twice in a federal court on the charge of use of excessive force - both times the jury failed to reach a unanimous decision. The incident in February this year left Sureshbhai Patel partially paralysed. In an exclusive interview with the BBC, Mr Patel's family say they hope the officer involved, Eric Parker, goes to prison for what happened. Mr Parker is still awaiting trial for a state charge of third degree assault. The family is also suing for damages. The policeman says he didn't mean to hurt Mr Patel, but acted in the interests of officer safety. The case made international headlines - the Indian government raised concerns, prompting an apology from the Governor of Alabama.
